HAGERSTOWN, Md. (AP) -- Maryland authorities say snow removal efforts on Interstate 81 in Washington County were delayed for hours because of a chain-reaction accident involving more than 20 vehicles.
State police say the highway was closed in both directions for about three hours following the crash. It started around 11:30 a.m. Sunday, when a tractor-trailer ran into the median to avoid cars that had spun out. It was hit by another tractor-trailer that overturned and spilled its load. Several other tractor-trailers ran off the road and jackknifed as their drivers tried to avoid the crash.
Police did not report any life-threatening injuries as a result of the crashes. Several vehicles have been left in the median and won't be removed until conditions improve.
Authorities are urging drivers to stay off the roads.
